  1. The viability of roX1 roX2/Y; msl1/+; [w+ GMroX1-75C]/+ males was measured when the only source of roX RNA was the autosomal transgene. In each case the progeny were from roX1 roX2 mothers mated to roX+/Y; msl1/CyO; [w+ GMroX1-75C]/[w+ GMroX1-75C] fathers. The CyO progeny were discarded and the fraction of msl1/+ sons and daughters was compared. The first column indicates which msl1 allele was used. The middle column shows the percentage male viability compared to their sisters, and the right column gives the number of msl1/+ females recovered in each cross.
